, Specification ofLetters Patent.

To all whom z'tmdy concern ments in Rims. with MovableBotto'ms; and

I. do hereby declare the following to' be a full, clear, and exactdescription of the in-' mounted therefrom by invention ,consists infully forming-a part of this specification,

:. like numerals designate I views z- Fi of a vehicle wh mounted; Fi 4is a taining; .riiig'; and

' Sada vention,'such as will enable others skilled inthe art to which itappertains to make and use the same. p The present invention relates towheel rims and tires tot ytehicles, especially automobiles, and has'forits purpose to provide a construction wherein a permanent rim may havethe tire mounted thereon 'or de a simple and quickly performedoperation.

The invention is especially'applicable to wheel rims and tires of theclenchertype, tire sustain-.

and also'serves tosecurelyj hold the clencher elements in lockingengagement. H With these andother objects in view the the novel detailsof construction and combi'nationsof parts more hereinafter disclosed andparticularly inted out in the claims. Referring to the accompanying inwhich like parts in all the e- '1 is a side elevational view eelequipped with the present, improvement; Fig. 2 1s a central sectionalview illustrating the initial step of mounting the tire on'thewheel;Fig. 3'is a central sectional view showing the" tire transversesectional vie taken through the'tire and rim and showgig the valve;Fig... 5- is a similar view eel, and showing the securing device; Fig. 6isa transverse sectional view taken at. a point intermediate of 1 thetire valve-andring securing device; Fig. 7 is a detail viewi insideelevation of the tire sus- Fig. 8 is a central sectiona'ljviewofthesame.

: ffi l'erri'ngto the construction in detail, 1

designates the wheel telly, .inanently mounted the r1m 2 of the clenchertype, and whichlhas a relatively deep trough ted to receivethe tiresustaining ring 7 ermit a free independent movement Fior a purpose tohepresently stated.

the w a an thereo 9, serves to hold the ring viz,

drawings The means ed bolt 14' that is secured valve is at the top, ason which is per-v p I rat-enteesan. is. rare. Application filed Januarye, 1913. Serial no. water.

The tire comprises the usual'innertube I 5 and outer covering or shoe 6having wired beaded edges 7 that engage and interlock with the clencherelements 8 of the rim 2 in the usual manner. The inner tube 5 isprovided with the usual valve 9 that passes through a guiding to thering 4, anld-is protected thereby. The plate 11 of the valve serves tokeep the heads 7 of the tire cover in engagement with the clenchers 8 ofthe rim when the inner tube 12, havingis deflated. And the valve ca awinged nut 13 scrcw-threade onlthe valve the valve plate 11 against thebeads of the cover, as willbe understood from-an. inspection of Fig. 4of the draw ings.

tube or' socket 10 secured The sustaining rin 4: is of" endless rigidmetal and substantia ly fiat throughout, as illustrated in Figs. 7 and8. Said ring is 2, and 'n that position engages" with the inner tube 5and the beads 7 and sustains the tire cumference,'and also for its fullinner-cirlocated within the'trough 3 of thewheelrim of the cover,v

holds the beads? of the tire cover in secure engagement with theclenchers 8 of the wheel rim. A portion of that part diametrically op-'posite the socket 10,-has the sideedges therefunction of said flanges12is to serve as a guard (see Fig. 2'), 13eo'f the beads 7 from'beingcaught by the ring 4: when the tire isbeing mounted.

for securingthe' ring4 to pre '85 of turned inwardly to provide flanges12, I which are gradually tapered as shown. The

and preventthe edges vent that member from slipping relatively to-thewheel rim, consists to said ring at the flanged portion thereof,

in a socket piece of a screw-thread-- .95 Saidboltfits with I 15 on thewheel felly 1 with the smallest amount of play therein, and 1's.

diurm of a winged nut lfiscrew-threadedon said bolt.

The operation of mounting or dem untQ-QE ing the tire isfsubs'tantiallyas. follows:

The inner tube being'slightly inflated;

in- Fig. 2. The beads of the tire cover are then introduced between iwheel is turned until the socket/10 -of:the,.

17 on the telly 1. In

position, the sustaining ring and .tiretrough, as in securedto the wheelfelly' through the "me said socket 10 is tted to make the ring and thethe center then1- selves in the rim, which they will obviously dothrough their own weight when the wheelis turned as stated. The beadsthen take their proper position in the elenchers of the rim when thetire is inflated, as in Fig. 3. The ring is then-secured in positionwithin the trough of the rim by screwing up the nut 13 on the valve 9,and the nut 16 on the securing bolt 14. To demount the tire, theoperation just stated is performed in the reverse order.

It is obvious that those skilled in the. art may vary the details ofconstruction and arrangement of parts without departing from the spiritof my invention, and therefore I do not Wish to be limited to suchfeatures except as may be required by the claims.

What I claim is 1. In a vehicle wheel the combination with atrough-shaped rim having edges hooked over inward and adapted to engagethe edges of a clencher. tire, of a continuous ring mounted in thetrough-shaped portion of said rim and adapted, toengage the innerportion of the tire, with means for centering said ring in said rim andholding it in the projecting inwardly from said ring and adapted toreceive the valve stem of the tire, a screw-threaded bolt projectinginwardly fromsaid ring opposite to said sleeve, and

passing through the rim, and a nut engaging said bolt, substantially asdescribed.

2. In a vehicle wheel the combination with a trough-shaped rim havingedges hooked over inward and adapted toengage the edges of a clenchertire, of a continuous ring mounted in the trough-shaped portion of saidrim and adapted to engage the inner portion of the tire, with means forcentering said ring in said rim and holding it in the either side ofsaid bolt, and a nut engaging said bolt, substantially as described.

3. In a vehicle wheel the combination with a ,felly band, of atrough-shaped rim secured thereto, a continuous ring mounted in thetrough-shaped portion of said rim and adapted to engage the innerportion of the tire,'with means for centering said ring in said rim andholding it in the centered position, comprising a hollow sleeveprojecting inwardly from said ring and adapted to pass through the rimand felly band and also to receive the valve stem, a screw-threaded boltprojecting inwardly from said ring opposite .to said sleeve, and'ndaptedto pass through the rim and fellv band, and a nut engaging said bolt,substantially as described.

4:. In a vehicle wheel the combination with 'a felly band, of atrouglrshaped' rim secured thereto, a continuous ring mounted in thetrough shaped portion of said rim and adaptedto engage the inner portionof the tire, with means for centering said ring in said rim and holdingit in'the centered position, comprising a hollow sleeve projectinginwardly from said ring and adapted to pass through the rim and tellyband and also toreceive the valve stem, at screw-threaded boltprojecting inwardly from said ring opposite to said sleeve, andadapted'to pass through the rim and felly' band, the said ring beingprovided with crescent-shaped flanges at either side of said bolt,;and anut engaging said bolt, substantially as describe-c.

In testimonywhereof, I affix my signature, in presence of two witnesses.v
